T0 aZZ whom 'it may concern.'

Be it known that I, ORTON G. RUST, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Display Devices, of which the following is a specication, reference being had therein to the accompanying drawing.

This invention relates to display devices and is designed more particularly for use in displaying charts such as are employed 1 n school rooms and similar places to exhibit exercises, educational matter and information of various kinds. i

The object of the invention is to provide a device of this kind upon which a plurality of charts may be mounted in such a manner that they may be shifted from one position to another, thereby enabling different charts to be displayed and also enabling both sides of the same chart to be displayed; to so construct the device that the charts can be moved from one side thereof to the other without removing the same from the hangers and that the supporting devices or hangers for the charts may be adjusted to present either side thereof to the audience without moving the device as a whole; and further, to provide means whereby a selected portion of the matter on a chart may be displayed and other portions thereof concealed from view. It is possible to mount on a device of this kind a series of charts having thereon subjects matter which it is desired to use at different times and to display the desired subjects matter at the desired time without removing any of the charts from the display device.

It is a further object of the invention to provide such a device in which the individual charts can be readily placed in position and removed, thereby enabling the charts to be changed to eliminate matter which is no longer needed and to add new matter.

In the accompanying drawings Figure 1 is a side elevation of an apparatus embodying my invention; Fig. 2 is a top plan view of the same; Fig. 3 is a perspective view of one of the hangers and a chart and Fig. 4 is a transverse sectional View of a supplementary device embodying a modified form of the invention.

In these drawings I have illustrated one embodiment of my invention and have shown the same as comprising a pedestal consisting of a base l and an upright member or standard 2. Upon the upper end of this standard is a supporting device for the charts preferably comprising a frame 3 having thereon a series of hangers 4. As here shown the frame consists of a longitudinal member rotatably mounted upon the standard 2, and the hangers 4 are preferably in the form of rectangular loops of heavy wire or the like, and are rigidly secured midway of the lower portions thereof to the bar 3. This connection may be made in any suitable manner. In the present instance the bar has been slotted as shown at 5 and the hangers inserted in the respective slots and soldered, thus retaining the same rigidly in an upright position. The hangers are each provided with openings to permit the attaching and removal of the charts. The charts are shown at 6 and each is provided along its upper edge with a series of reinforced openings 7. In the present arrangement of the hangers the ends of the bar or wire of which each hanger is formed are arranged near the center of the upper portion of the hangers and spaced apart a distance suflicient to permit the insertion of the edge of the chart, thereby enabling the end of the rod forming the hangers to be inserted through the corresponding openings 7 in the chart. This space between the ends of the rod is-normally bridged by a ferrule or sleeve 8 which is slidably mounted on the rods and is of such a length that it may be moved beyond the opening to permit the charts to be inserted or removed, or may be moved across the opening to close the same and prevent such insertion and removal. It may be held in adjusted positions in any suitable manner but preferably it is mounted snugly on the rod forming the hanger and will be retained in position by the friction between the same and the rod until force is applied thereto. I/Vith this arrangement of the hangers it will be obvious that the charts can be readily transferred from one side of the supporting frame 3 to the other side thereof and that when moved from one side to the other the chart will be reversed, that is, the side which was formerly concealed will be exposed. This permits of the utilization of both sides of the chart, thereby doubling the capacity of the apparatus. I also employ in connection with the display frame a series of screens or blinders which may be moved in front of portions of the chart which is on display to conceal parts of the subject matter thereof= and to cause only a selected portion or portionsthereof -to be exhibited. In the present instance I have shown three of these screens which are indicated by= the reference numeral 9 in Figs. 1 andl 2. In Fig. 1 two only of the screens are in use, these being arranged to exhibit between them a portion only vof the chart and to conceal those portions immediately above and below the selected portion, thereby concentratingv the attention of the observer or student upon this part ofthe chart. y

As many screens may be employed as is desired or as is necessary to conceal the dcsiredv portions of the chart. These .screens may be supported in adjusted positions by any suitable meansl but in the present construction of the device the apparatus is pro,- vided with frame members 10 arrangedv on opposite sides of the standard 2 at thel vertical edges of the charts and preferably supported by a frame member or bar 11 rotatably mounted upon the standard 2. The upper ends of these frame members are connected to the horizontal supporting frame 3. This connection may be formed in any suit.- able manner and as here shown the frame member 3 is made up of two bars arranged close together and having their end portions bent in opposite directions and adapted to extend about the frame members 10 as shown at 12 in Fig. 2. Secured tothe inner side of the frame members are guides 13 which cooperate with flanges 14 on the frame members to form guideways l5 in which the screens 9 are slidably mounted. These flanges of the end pieces are provided with a series of holes 16 yadapted to receive pins 17 upon which the screens rest and which may be moved from one pair of holes to another to, support the screen in adjusted positions. Thev two bars making up the frame member 3 are here shown as bent outward at the central vportion to form a socket. 1S in which is rigidly secured a stud 19 which extends into the recessed upperV end of the standard 2 and coperates therewith to form the pivotal connection between thestandard 2 and the supporting frame 3. In order that the outermostV chart on either side of the frame may be supported close to the screens I have shown the central parts of the lower portions of the several hangers as bent upward so that the bottom wall of the hanger slopes outwardly from the center and on both sides thereof, thereby causing the charts to. gravitatey toward the outer ends of the hangers: andto'be supported close to the screens.

In connection with the device just described I prefer to employ a supplementary "device which has in part the function of the main device but further serves as a storage receptacle inwhich the charts may be stored when not in use. As here shown the supplementary device comprises a cabinet having two parts, one of which constitutes the storage receptacle, as indicated -at 20, and the other of which constitutes a display frame, as shown at 21. In this latter part of the cabinet there are provided aseries of pins 22 to enter the openings 7 in the charts and to support the charts in a vertical position. The edges of the display portion of the cabinet are extendedforwardly and are. provided with? flanges 23 in which are mounted pins 21 which adjustably support the screens 9,y in the same manner and for the same purposes as they are shown in Figs. 1 and 2. The storage receptacle 20 may be of less heightl than the display portion of the frame and is preferably provided with a door 25. hinged at its lower edge and providedwith.` two or more pins 26 to. enter corresponding openings of the charts and support the same in vertical positionswhen the door is closed.l To facilitate the placing of the charts in position on the pinsand the removal of the same therefrom I provide means, such as a frame 27 having a transverse bar 2.8 to support the door in a substantially horizontal position with the pins extending upward as shown in Fig. 4. This arrangement, enables the charts toy be taken from the receptacle, displayed and returned to the receptacle with very little inconvenience. Y f

The construction and use of the apparatus will be readily understood from the foregoing descriptionand it will be apparent that with it a series of charts may be supported and these charts adjusted on the hangers to display a given one Vof said charts and todisplay either side of the selected chart, this being accomplished by moving the charts from one side. of the supporting frame to the other side thereof and when the desired side of the selected chart has been exposed to view to rotate'the supporting frame to.

place that portion of said chart inl a position to be observed by the school or audience. Further, Vby an adjustment of the screens given portions of the displayed chart may be concealed from view and selected parts thereof may be exposed in such a manner as to concentrate attention thereon. By means of this apparatusV the entire chart or any selected part thereof may be exposed or studied or thel entire chart may be concealed Y and it permits of the carrying on the apparatus at one time a yearly feature for daily use such as. a morning exercise; al daily or Sessional featuresueh as a quotation orselec-- tion of some sort which it is desired 'to use once 'on-ly; a periodical feature which it is desired to use at intervals only, say once a Week and any other arrangement or grouping of features, and enables these features to be quickly and easily displayed When desired. Further, the device permits of the ready attaching and removal of the charts, thereby enabling a chart which is no longer needed to be removed and new matter substituted therefor. This interchangeability of the charts gives the device a Wide range of utility and enables it to be used for displaying current topics and matters developed by original research as Well as for displaying standard eXercises, quotations and the like which are used repeatedly.

While I have illustrated one embodiment of my invention, it Will be understood that this is chosen for the purpose of illustration only and that I do not Wish to be limited to the details of the construction shown and described for obvious modifications Will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
